is there any way to create a single image on the home page in a larger size like 500px x 200 px??!?!?! I just want something fun --not relevant to specials or featured items.....

URL is www.expressionsphotostore.net , right now it is set to 4 featured images...but I want to take them out and replace them with jsut one artsy image....

I have also spent way too many hours trying to figure out how to make the upper right menu an inline navigation to run horizontal...can anyone direct me anywhere on this one??!?!

THANK YOU!!!!
